Heroes for Hope

October 13, 2018, 10 a.m. – 7 p.m., Ramsey

Join us for a day of fun out at the farm! Enjoy hay rides, a corn maze, professional family photos, a silent auction and more all to support Heroes for Hope. This endowment was founded when three families came together to honor their heroes. Vito, Lejla and Gavin all fought brain cancer at Children's Minnesota with the help of the amazing Cancer and Blood Disorders Team. We hope to help other families in their fight.

About the Brain

Before you can understand about brain and spinal tumors, it’s helpful to understand the anatomy of the brain and spine and how they function.

Optic Pathway Glioma

An optic pathway glioma is a subset of low grade astrocytoma that grows in a portion of the optic pathway (optic nerve, optic chiasm, optic radiations).  Optic gliomas typically grow as an infiltrative lesion with poorly defined borders.  Because they are infiltrative they often extend and involve the entire optic pathway.  They also frequently extend into adjacent structures, such as the hypothalamus. Optic chiasmatic and hypothalamic gliomas are often considered a single entity because of their ability to infiltrate into both compartments regardless of the site of origin of the tumor.  These tumors originate from astrocytes, which are star-shaped brain cells.  Astrocytes are a type of glial cell which function to support the surrounding cells. Optic pathway/hypothalamic gliomas account for 4-6% of all brain tumors in children and 30% of all pediatric gliomas.  The peak incidence is during the first decade of life.

Intracranial Germ Cell Tumor

Germ cell tumors (GCTs) arise from primordial germ cells that did not migrate appropriately during embryonic development.   Residual primordial germ cells deposited in the brain give rise to intracranial germ cell tumors.  These residual primordial germ cells tend to be located in the midline of the body; therefore intracranial germ cell tumors typically originate in the suprasellar or pineal region.  Rarely GCTs originate in other midline intracranial locations including the basal ganglia, thalamus, and ventricles.  Intracranial germ cell tumors are twice as likely to be located in the pineal region compared to the suprasellar region.  Approximately 5-10% of cases have “bi-focal” disease, defined as simultaneous involvement of the suprasellar and pineal region.  Intracranial germ cell tumors mainly occur in adolescents and young adults (peak incidence is 10-12 years of age) and are more commonly seen in boys.  These tumors have the capacity to spread (metastasize) through the spinal fluid (leptomeningeal spread).

Medulloblastoma or PNET

Medulloblastoma (also referred to as primitive neuroectodermal tumor or PNET) arises from the primitive or embryonal cells of the cerebellum. Medulloblastoma is a tumor that arises within the cerebellum and often grows into the fourth ventricle. These tumors have the capacity to spread (metastasize) through the spinal fluid (leptomeningeal spread), occurring in approximately 30% of cases, and they rarely spread to bone and bone marrow.
